Older gas furnace with standing pilot light, new thermocouple Burners will NOT light
Hello,
I am at the end of my rope. I have an older Armstrong Air (Honeywell) standing pilot furnace. The pilot light is a strong blue flame. The thermocouple is about 20 min old. (I just replaced it thinking that was the problem). The thermostat seems to be working properly. When I set it to heat the little exhaust blower comes on, but that's all that happens. The main burners never light. Any guesses? I don't have money for a service call.
